I have a 04 and it runs for 45 or so mins, then dies. i wait for a little bit, starts up runs for a little bit dies again etc etc, a mechanic said something in the electrical harness, could be whole harness or just a wire, wondering if anyone had same troubles. any help would be great.

My car runs for half hour, dies, i have to charge the bat over night then it'll run for another 45mins or so, its not my alt, was thinking the engine harness? any advice or if someone experienced same problems?

Crank Sensor perhaps?

It would be nice if you had a scantool, that way you can make a movie of the data and see which PID you lose when the car dies..
